摘　　要：目的:探讨连续波热牙胶充填后牙弯曲根管的临床效果。方法:选取2012年1—12月在我院牙体牙髓科确诊为牙髓病或根尖周病的后牙弯曲根管80例,根据患者的治疗意愿分为两组,即热牙胶组和冷侧压组(每组40例),所有患牙常规开髓,Mtwo机用镍钛系统预备根管,氢氧化钙糊剂消毒。热牙胶组采用连续波热牙胶垂直加压技术进行充填,冷侧压组行冷牙胶侧方加压充填,根充后即刻摄片检查充填情况。观察根充恰填率、侧副根管充填情况,术后1周疼痛反应,1年后成功率。结果:热牙胶组恰填率为95.00%,冷侧压组恰填率为77.50%,热牙胶组恰填率明显高于冷侧压组,差异具有统计学意义(P<0.05);热牙胶组侧支根管的充填率15.00%(6/40),冷侧压组0.00%(0/40),两组比较差异具有统计学意义(P<0.05);术后1周复诊,热牙胶组与冷侧压组疼痛率分别为12.50%和22.50%,差异无统计学意义(P>0.05)。术后1年复查疗效,热牙胶组成功39例(97.50%),冷侧压组成功31例(77.50%),热牙胶组优于冷侧压组(P<0.05)。结论:连续波热牙胶充填术优于冷牙胶侧方加压充填术,患者术后疼痛的发生率低,治疗效果更好,值得临床广泛推广。Objective： To investigate the continuous wave warm gutta-percha in filling molar curved root canals of clinical effect. Methods： From 2012 January to 2012 December in our hospital dental diagnosis of molar curved root pulposis and pe-riapical disease canal in 80 cases,the patients will be divided into two groups,namely warm gutta-percha group and cold side pressure group（40 cases each group）, all teeth conventional open pulp,nickel titanium system in root canal preparation by us-ing M-two machine, Calcium Hydroxide Paste disinfection. Warm gutta-percha group using continuous wave warm gutta-percha vertical compaction technique for filling , cold side group underwent cold lateral condensation of gutta-percha filling , root canal filling after radiography examination. To observe the proper filling rate , lateral root canal filling 1 weeks after oper-ation, pain reaction, the success rate of 1 years. Results： The warm gutta-percha group just fill rate is 95%, the cold lateral condensation group just fill rate is 77.50%, warm gutta-percha group just fill rate was significantly higher than that of cold pressure group, the difference was statistically significant （P〈0.05）, warm gutta-percha lateral root canal filling rate was 15%（6/40）,cold lateral condensation of group was 0% （0/40）, difference between the two groups was significant（P〈0.05）, after 1 weeks, the rate of pain warm gutta-percha group and cold side group were 12.50% and 22.50%（P〉0.05）. Follow-up after 1 years, warm gutta-percha group was successful in 39 cases（97.50%）, the cold side group was successful in 31 cases （77.50%）, the difference was statistically significant（P〈0.05）, warm gutta-percha group is better than the cold side group. Conclusion： Continuous wave warm gutta perchafilling was better than cold lateral condensation of gutta-percha filling opera-tion,postoperative pain in patients with low incidence, treatment effect is better, is worthy of clinical application.
